FIELD OF THE INVENTION

The invention generally relates to bedding, and more particular to a mattress with breathable and ventilation functions.

BACKGROUND OF THE INVENTION

Sleep is critical for people in every aspect of their lives. A bed mattress is an instrument for sleeping which provides a cushion or a buffering force using cushion members, such as memory foams.

Memory foam mattresses are widely considered to be a superior product for users, because of the ability of a foam mattress not only to conform to user's body shapes, but also to be readily compressed and packaged in a size that is manageable for transportation. However, a memory foam mattress may retain a user's heat, thereby causing the user to get hot during sleep. Heat retention in a mattress is generally undesirable to a majority of users.

Thus, it is beneficial and desirable for people to have a bedding system that is capable of adjusting body positions and bed temperature based on user's sleep preference, so that the user achieves maximum comfort during sleep.

For purposes of clarity, the same reference numbers will be used in the drawings to identify similar elements. It should be understood that one or more steps within a method may be executed in different order (or concurrently) without altering the principles of the invention.

The description will be made as to the embodiments of the invention in conjunction with the accompanying drawings in FIGS. 1-8. In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to a mattress with breathable and ventilation functions.

Referring FIGS. 1-5, a mattress 100 is schematically shown according to one embodiment of the invention. The mattress includes a plurality of layers 110-150 vertically stacked to one another.

The plurality of layers includes a first layer 110, a second layer 120 disposed on the first layer 110, a third layer 130 disposed on the second layer 120, a fourth layer 140 disposed on the third layer 130; and a fifth layer 150 disposed on the fourth layer 140. It should be noted that other number of layers can also be utilized to practice the invention.

As shown in FIG. 2-4, the first layer 110 comprises four openings 111-117 defined in the first layer 110. The openings 111-117 are operably in fluidic communication with a plurality of fans for providing air circulation to a user through the mattress (FIG. 8). It should be noted that other number of openings can also be utilized to practice the invention. In some embodiments, the first layer 110 is formed of a flex support foam for providing corner to corner support, and ensuring a deeper, more regenerative night's sleep. In some embodiments, the first layer 110 has a thickness in a range of about 2-3 cm.

As shown in FIGS. 1-3 and 5, the second layer 120 is arranged between the first layer 110 and the third layer 130 and comprises an array of springs 125. The array of springs comprises a specially fitted hybrid support-springs to provide breathable, ventilation and thorough foundation. In some embodiments, the array of springs comprises a plurality of pocket springs 125, or coil springs. In some embodiments, the array of springs comprises about 1500-2500 pocket springs, preferably 2000 pocket springs.

As shown in FIGS. 1-3, the second layer 120 also has four side walls 121-124 defining a housing therewith for accommodating the array of springs 125. Each of the four side walls 121-124 can be formed of a flex support foam.

In some embodiments, the second layer 120 has a thickness in a range of about 12-20 cm.

The third layer 130 is formed of a flex comfort foam, which adds an additional layer of comfort to create a more breathable and supple feel.

In some embodiments, the third layer 130 has a thickness in a range of about 2-3 cm.

The fourth layer 140 is formed of a ventilated bamboo charcoal memory foam. The ventilated bamboo charcoal memory foam comprises a memory foam infused with bamboo charcoal, for regulating moisture, odor and/or temperature, and adapting to user body's individual points.

The fifth layer 150 is formed of a smart foam that is breathable, flexible and operably adapts to user body's natural contours. It also provides all of the benefits of the latex whilst being allergy free.

In some embodiments, each of the fourth layer 140 and the fifth layer 150 has a thickness in a range of about 2-5 cm.

In addition, the mattress 100 may also have a cool knit fabric cover for covering the plurality of layers 110-150, so as to enhance air-flow and breathability, creating a cooler, more deep sleep.

In addition, the mattress can be of any sizes, for example, a king size, a queen size, a full size, a twin size, or a customized size, by changing its width, W, and its length, L, as shown in FIGS. 4 and 6.

FIGS. 6-7 shows schematically a mattress 100′ according to another embodiment of the invention. The mattress 100′ is similar to the mattress 100 shown in FIGS. 1-5, except that the size of the mattress 100′ is different from that of mattress 100 and the first layer 110′ has two openings 111′ and 113′ defined in the mattress 100′. It should be appreciated that other number of openings, e.g., three openings, five openings, etc., can also be utilized to practice this invention.

Unlike traditional memory foam, the mattress according to the invention provides ventilation for superior airflow and temperature regulation. This added breathability means a user can rest more comfortably.

FIG. 8 shows schematically a cross-sectional view of an adjustable bed system with the mattress 100′ according to one embodiment of the invention. The adjustable bed system includes a frame structure 180, one or more platforms (or bed boards) 170 moveably connected to the frame structure 180, a first lifting assembly 191 and a second lifting assembly 192 moveably connected to the frame structure 180.

One of the first lifting assembly 191 and the second lifting assembly 192 is a back lifting assembly, and the other of the first lifting assembly 191 and the second lifting assembly 192 is the leg lifting assembly. For the purpose of illustration, the first lifting assembly 191 is the back lifting assembly, while the second lifting assembly 192 is the second lifting assembly 192. When the mattress 100′ is disposed on the platforms 170, the upper (back) portion and the lower (leg) portion of the mattress 100′ are in relation to the back lifting assembly 191 and the leg lifting assembly 192, respectively, and positions of the upper portion and the lower portion of the mattress 100′ are individually and/or coordinately adjustable in accordance with operations of the back lifting assembly 191 and the leg lifting assembly 192.

The back lifting assembly 191 comprises a back lifting bracket 191 a pivotally connected to the frame structure 180, and a back lifting actuator 191 b pivotally connected between the back lifting bracket 191 a and the frame structure 180 for operably driving the back lifting bracket 191 a to pivotally move in an upward rotating direction or a downward rotating direction relative to the frame structure 180. Such pivotally moving of the back lifting bracket 191 a causes the back portion of the platforms 170 and therefore the back portion of the mattress 110′ to be lifted up (e.g., in a lift portion, not shown) or lifted down (e.g., in a flat position shown in FIG. 8).

The leg lifting assembly 192 comprises a leg lifting bracket 192 a pivotally coupled to the frame structure 180, and a leg lifting actuator 192 b pivotally connected between the leg lifting bracket 192 a and the frame structure 180 for operably driving the leg lifting bracket 192 a to pivotally move in an upward rotating direction or a downward rotating direction relative to the one of the frame structure. Such pivotally moving of the leg lifting bracket 192 a causes the leg portion of the platforms 170 and therefore the leg portion of the mattress 110′ to be lifted up (e.g., in a lift portion, not shown) or lifted down (e.g., in a flat position shown in FIG. 8).

The adjustable bed system also has two fans 161 and 163 that are mounted onto corresponding openings in the platforms 170, such that when the mattress 100′ is placed on the platforms 170, the openings 111′ and 113′ in the first layer 110′ of the mattress 100′ are aligned with and are in fluidic commination with the two fans 161 and 163, respectively. In operation, the two fan 161 and 163 can individually or cooperatively move air (i.e., air flow or air circulation as indicated by arrows in FIG. 8) via the openings 111′ and 113′ into the mattress body and outputting the air from the top surface of the mattress 110′.

Specifically, each fan 161/163 is configured such that in operation, air is flown from the rear side of said fan 161/163 to the 111′/113′ of the mattress 110′, then spread through the mattress body and output from the sleeping surface (i.e., the top surface) of the mattress 110′, as illustrated by arrows shown in FIG. 8. The air can be room temperature air, cooling air or heating air.

In addition, the strength of the air flow or air circulation is adjustable by individually or cooperatively operating the fans 161 and 163, based on the user's preference. The operation of the fans 161 and 163 can be automatically controlled, or manually controlled via a remote control. The operation can also be controlled via an AAP.
